Red Hair Gene

Postby Olathe » Tue Mar 27, 2012 6:52 pm

Hello. I am searching for an answer to a question I have, and I wasn't sure where to put it, so here it is.

I have 5 biological full siblings (from what I have been told). I have brown hair, my oldest sister has brown hair, and both of my younger sisters have blond hair (that seems to be turning brown). I also have 2 brothers who have red hair -- very red hair.

My mother is a red head, and my father has brown/black hair. My grandparents on my mother's side have blond hair, and brown hair, and my grandparents on my father's side have the same. I do not know the hair colors further, but I can find out if needed.

My husband says my father can't carry a red hair gene, and you need a gene from both the mother and father to produce a child with red hair, is this true? Can anyone explain it further? Are my brothers actually half-siblings?

Any help is greatly appreciated! Thanks. :D

As I recall red hair in humans is a recessive trait so your father could well be carrying a red hair gene. Unless you have a red haired mail carrier?
